[Aspuru-Guzik Group List] Fwd: Welcome to QUTE - Advanced Quantum Technologies

by Alan Aspuru-Guzik

Dear all, I am in the editorial board of this new journal, which being part of the Advanced X series of Wiley (e.g. Advanced Functional Materials) promises to be high-impact. Keep it in mind when we decide where to send our quantum papers.

It currently comprises the proud number of 40 international members. You should now all be mentioned at http://onlinelibrary.wiley.com/journal/10.1002/(ISSN) 2511-9044/homepage/2820_edbd.html. (Please check if the listed information is complete and let us know if you require any changes.) To reiterate what we have formulated as journal scope: *Advanced Quantum Technologies* is an international, interdisciplinary journal for peer-reviewed, high-quality, high-impact theoretical and experimental research in the fields of basic and application-related quantum-based communication, computation, control, engineering, information, metrology, optics, sensing and simulation, as well as related areas such as nanophotonics, quasiparticle excitations, topological materials, superconductors, micro- and nano-electromechanical systems, ultracold atoms and others. Core information on Advanced Quantum Technologies may be found on our news portal Advanced Science News at http://www.advancedsciencenews.com/ advanced-quantum-technologies, including an extensive* keyword list* at the bottom of the page, in which some of your recent suggestions have also been included. (Obviously further refinements or extensions of this information are possible.) Feel free to forward this link to your colleagues and collaborators. The journal homepage is http://www.advquantumtech.com. It is open for submission at http://www.editorialmanager.com/advquantumtech - the first few manuscripts have been received. The Editorial Office can be contacted by e-mail at advquantumtech(a)wiley.com. Our editorial team comprises Matteo Cavalleri, Hoboken; Maria E. Stournara, Berlin; Huan Wang, Beijing and myself as Editor-in-Chief. We would like to bring the new journal on track as soon as possible and therefore hope for your support. Please spread the news about QUTE in your community and region. Ideally we would appreciate if you and/or your collaborators/colleagues could submit a paper within the next ~3 months – a regular research paper (Communication, Full Paper) or a proposal for an overview article (e.g. Review or Progress Report). Please also provide further suggestions for potential authors and topics that should be covered in the journal. At the symposium on “The Second Quantum Revolution” last week in Berlin I was asked to describe the aim of the new publication within one sentence, especially for those communities that are not so familiar with the Advanced journal concept. Perhaps a few bullet points should do: *high quality – topical relevance – high visibility* – which should ultimately also generate good citation levels. While we will adopt a strict and professional peer review process with expert assessments we do not strive for breakthrough work only – this might be quite inappropriate for a journal that has not even launched yet. So QUTE should also be open for specialized and interesting technical work, both basic and applied, theory and experiment, as long as the results are unpublished and new. In that sense we are looking forward to your and many other contributions to Advanced Quantum Technologies!

[Aspuru-Guzik Group List] [qip] QIP special seminar ... Monday, Nov. 21

by Peter Shor

Beth Ruskai will be giving a seminar on Monday, Nov. 21 at 4pm. Details follow. -------- Speaker: Mary Beth Ruskai Title: Using local additivity to find examples of superadditivity of quantum channels. Room: 6C-442, MIT. Time: 4pm, Monday November 21. Abstract: The local additivity of minimal output entropy can be extended to local additivity of maximal relative entropy with respect to a fixed reference state. This can be exploited to test channels for superadditivity of Holevo capacity with numerical effort comparable to searching for the minimal output entropy. Local maxima which do not arise from product inputs play a key role. Moreover, evidence of superadditivity can be found even if the additivity violation itself is too small to be seen numerically. This talk will be divided into two parts. First we sketch the Gour-Friedland proof of local additivity with several significant simplifications. Second, we describe a program to test 3-state qubit channels for superadditivity of the Holevo capacity. _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik Group List] ITAMP lunch seminar, 12pm Nov 16th, Michal Tomza (Warsaw University)

by Hannes Pichler

ITAMP Lunch Seminar Speaker: Michal Tomza, (Warsaw University) Date: Thursday, November 16th Time: 12:00-1:00 pm Includes Pizza. Title: Quantum-chemical approach to few-body quantum systems Abstract: In the first part I will present the application of the quantum-chemical coupled-cluster method to study the properties of a balanced two-component Fermi gas in a one-dimensional harmonic trap. For few fermions we recover the results of exact diagonalization, yet with this method we are able to study much larger systems. We compute the energy, the chemical potential, the pairing gap, and the density profile of the trapped clouds, smoothly mapping the crossover between the few-body and many-body limits. The energy is found to converge surprisingly rapidly to the many-body result for every value of the interaction strength. Many more particles are instead needed to give rise to the nonanalytic behavior of the pairing gap, and to smoothen the pronounced even-odd oscillations of the chemical potential induced by the shell structure of the trap In the second part I will present our investigations of two interacting ultracold polar molecules described as distinguishable quantum rigid rotors effectively trapped in a one-dimensional harmonic potential. The molecules interact via a multichannel two-body contact potential incorporating the short-range anisotropy of intermolecular interactions. The impact of external electric and magnetic fields resulting in Stark and Zeeman shifts of molecular rovibrational states is also included. The importance and interplay of the molecular rotational structure, anisotropic interactions, spin-rotation coupling, electric and magnetic fields, and harmonic trapping potential are examined in detail and compared to the system of two harmonically trapped distinguishable atoms. Presented model and results may provide microscopic parameters for molecular many-body Hamiltonians and may be useful for the development of bottom-up molecule-by-molecule assembled molecular quantum simulators. Location: B-106 @ Center for Astrophysics (60 Garden Street) Directions: After entering the lobby of the CfA, turn right to enter the hallway of the B building. In the hallway, turn right again, B-106 will be at the end of the hallway on the left side.

[Aspuru-Guzik Group List] Klaus Robert Müller visit tomorrow

by Jennifer Wei

Hi everyone, This is a reminder that Prof. Klaus Robert Müller will be visiting the group tomorrow. He will give a talk at 11am, please see details below. We also have one meeting time with him at 9am in New Siberia for all group members that are interested in meeting with him. Jennifer ------------------------------------------------------------- Klaus-Robert Müller TU Berlin, Korea University, MPII Nov. 15, 11 - 12pm Maxwell Dworkin 119 The talk starts by gently introducing selected machine learning (ML) concepts useful for analysing data from atomistic simulations, namely kernel methods and deep learning. Based on this and if time permits, two applications of ML usage are presented (1) ML for predicting quantum mechanical properties across chemical compound space and (2) ML for molecular dynamics. Finally, the importance of understanding of ML models obtained from training on data of atomistic simulations is stressed.
